Description
Technical field
The present invention relates to cell art, specifically a kind of water filling magnesium alloy battery.
Background technology
Magnesium alloy electrode potential compared with kirsite is lower, electrochemical equivalent is less and conductivity is better, is more preferably battery anode material.But, because magnesium alloy electrochemical properties is too active, therefore series of negative effect (such as: voltage delay and the perishable perforation of housing etc.) can be produced when being used as battery anode material.In most of electrolyte solution, magnesium alloy dissolution velocity is very fast, produces a large amount of hydrogen, causes anode faradic efficiency to reduce.In addition, the existence of impurity element in magnesium alloy, accelerates magnesium alloy from corrosion reaction speed, generates and has certain thickness Mg (OH)
2passivating film, seriously inhibits magnesium alloy anode active dissolution.Therefore, the utilance improving magnesium-alloy anode material is focus and the difficult point of current magnesium alloy battery research, and its key problem in technology solves the contradictory relation between magnesium alloy anode activation and passivation.
Summary of the invention
An object of the present invention is to provide a kind of water filling magnesium alloy battery anode material, by measures such as material alloys modification and battery structure rational Design on Plane, solve the technical bottleneck of the water filling perishable perforation of magnesium alloy battery anode and voltage delay.
Water filling magnesium alloy battery of the present invention, comprises anode, catalyst and outer protection box hat that magnesium alloy is made.In described magnesium alloy, the addition of aluminium element is 0.2-10.0wt%, and the addition of Zn-ef ficiency is 0.2-3.0wt%, and the addition of manganese element is 0.1-3.0wt%, and all the other are magnesium elements.
Described catalyst is Powdered, is selected from magnesium chloride, magnesium nitrate, activation electrolytic manganese dioxide, water-absorbing resin, one or more in active carbon and sodium chloride.
A kind of preferred catalyst, comprise 1-10wt% magnesium chloride, 1-10wt% magnesium nitrate, 1-15wt% activation electrolytic manganese dioxide, 1-15wt% water-absorbing resin, 5-25wt% sodium chloride, all the other are active carbon.
The beneficial effect that technical solution of the present invention realizes:
Water filling magnesium alloy battery of the present invention has excellent storge quality, and under the condition of drying sealing, the storage life can reach more than 20 years.
